Izis can create beings from someone's desire. Shuna wished for a cuter Rimuru. Izis used Shuna as image and the abilities of Rimuru an thus Shinsha was born.
@@kodokutamashi1569 does that really mean that she he's daughter in real world something told me that and said your father I would say no because I never was part creation of the bein.I guess for rimura it blessing and curse bevmcause he can't really reproduce so he can adopt her and since that look alike it okay.
@@ezmelloanimegryt8190 I mean regardless of the physical appearance, Shinsha does have the same abilities and power as Rimuru so In any case it is her daughter
@@kodokutamashi1569 you could way dna wise she is the child of shuna and rimuru. being a slime. and inheir her color and horns. but neither of them birth her. so you could say she is a clone made from them.
